Thoroughly clean all traces of ARSENAL herbicide from application equipment immediately after use. Flush tank, pump, hoses and boom with several changes of water after removing nozzle tips and screens (clean these parts separately). Drain and flush equipment away from desirable trees and plants. Do not contaminate water when disposing of equipment wash waters.
This product is to be applied by licensed applicators only.
GENERAL INFORMATION
ARSENAL herbicide is an aqueous solution containing surfactant to be mixed in water and applied as a spray for season long control of most annual and perennial grasses and broadleaf weeds on non-cropland areas.
ARSENAL herbicide must be applied post-emergence to the weeds. For maximum activity, weeds should be growing vigorously at the time of post-emergence applications.
ARSENAL herbicide is readily absorbed through foliage and roots and is translocated rapidly throughout the plant. Treated plants stop growing soon after spray application. Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground storage organs, thus preventing regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until two weeks after application. Complete kill of plants may not occur for several weeks.
WEEDS CONTROLLED
ARSENAL herbicide will provide season long control of most annual and perennial grass and broadleaf weeds including the following species:

DIRECTIONS FOR USE Application Sites
A post-emergence application of ARSENAL herbicide can be used to control most annual and perennial grasses and broadleaf weeds on the following non-crop, non-graze areas: industrial sites, railroad ballast, spot application treatment for rail and hydro rights-of-way and stations associated with pipeline rights-of-way including well sites, battery stations, and compressor or valve stations. Do not contaminate ponds, lakes, streams, wetlands or sloughs and do not apply within 15 metres of a wetland area or body of water.
Rate
Apply 3.0 L ARSENAL herbicide per hectare. For small areas apply 30 mL per 100 m2 (see Table for examples).
LITRES OF WATER AMOUNT OF ARSENAL HERBICIDE AREA COVERED 1 5 10 20 50 30 mL 150 mL 300 mL 600 mL 1.5 litres 100 m2 500 m2 1,000 m2 2,000 m2 5,000 m2 MIXING INSTRUCTIONS
Mix the proper amount of ARSENAL herbicide in water in the spray tank with the agitator running.
A foam reducing agent may be added at the recommended label rate, if needed.
EQUIPMENT
High volume spray equipment: high pressure handguns and vehicle mounted high volume directed spray equipment
For best results, apply ARSENAL herbicide using the least amount of water practical to obtain uniform coverage of the vegetation foliage. Using excessive spray volumes which may cause runoff from the plant foliage may result in reduced performance. Apply uniformly with properly calibrated ground equipment in 100 - 550 litres of water per hectare with a spray pressure of 175 kPa - 425 kPa.
If using spray volumes greater than 550 litres per hectare, additional nonionic surfactant must then be added at a rate of 1 litre/400 litres of spray solution to provide optimum wetting and/or
Boom: conventional boom mounted, manifold mounted, and off-centered nozzles
Mix the recommended amount of ARSENAL herbicide in 100 - 550 litres per hectare in the spray tank with the agitator running. A foam reducing agent may be added at the recommended label rate if needed.
Low volume hand held equipment
Backpack, knapsack, and other pump-up type pressure sprayers and backpack mist blowers used to direct applications to weed foliage.
FORESTRY SITE PREPARATION APPLICATION SITE
ARSENAL herbicide can be used as a directed, spot or strip spray application for site preparation prior to planting spruce seedlings in the Boreal Forest Region only.
Effects of ARSENAL herbicide are slow to appear on target plants with maximum effectiveness generally being apparent more than one full growing season after treatment.
ARSENAL herbicide should be applied at least (6) months prior to planting spruce seedlings or injury may occur. Reentry Interval: DO NOT reenter treated area within 12 hours after application.
Consult local pesticide authorities about use permits which may be required.
SPECIES CONTROLLED
Aspen and bluejoint reedgrass.
RATE AND EQUIPMENT
When making directed or spot spray applications with low volume hand application equipment thoroughly mix a 2.5% solution of ARSENAL herbicide in water. Treat up to one half (1/2) the total area of the site preparation area by applying spots or strips to create planting sites. Evenly apply 8 ml of mixture per square meter of treated spot.
When making spot or strip applications using ground application equipment apply 2.08 L of ARSENAL herbicide in 75 to 100 L of mixture per treated hectare. Equipment should be configured to treat spots or strips totaling no more than one half (1/2) of the treatment unit (cut block plantation opening).
RESISTANCE MANAGEMENT RECOMMENDATIONS
For resistance management, ARSENAL herbicide is a Group 2 herbicide. Any weed population may contain or develop plants naturally resistant to ARSENAL herbicide and other Group 2 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Other resistance mechanisms that are not linked to site of action, but specific for individual chemicals, such as enhanced metabolism, may also exist. Appropriate resistance-management strategies should be followed.
To delay herbicide resistance:
• Where possible, rotate the use of ARSENAL herbicide or other Group 2 herbicides with different herbicide groups that control the same weeds in a field.
• Use tank mixtures with herbicides from a different group when such use is permitted.
• Herbicide use should be based on an IPM program that includes scouting, historical information related to herbicide use and crop rotation, and considers tillage (or other mechanical), cultural, biological and other chemical control practices.
• Monitor treated weed populations for resistance development.
• Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment and planting clean seed.
• Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.
